1 Claim. (Cl. 52-347) The present invention relates to an assembly of a house, other building, a room or the like with prefabricated wall elements, and especially to the individual elements and their production in series.

It has been found that the production of prefabricated wall elements according to the invention, as well as the production of the lining posts and also the filling up of the spaces-formed, can be done considerably simpler and quicker as well as with a saving in material in comparison with the procedures previously known, and this with a higher stability and heat insulation in the individual elements, and consequently in the whole assembly with prefabricated wall elements.

The assembly according to the invention by means of wall elements prefabricated in series with two lining posts which are joined to each other by plates secured on either side, said lining posts being nested by grooves and tongues laterally attached to these posts and said posts preferably being engaged by tongues in corresponding grooves of horizontal lining socles consists in that the lining posts of the prefabricated wall element comprise a middle post and two' jambs and three jambs respectively, laterally mounted on this middle post, the outer of which jambs always form the lateral grooves and tongues, while the inner jambs serve as supports for through paling boards which are reciprocally coated with insulating materials, and laths are flush mounted on either side of these layers and middle postts, the laths being horizontally directed and at a vertical distance from each other, i.e. for support ing the usual outer covers.

As to the assembly with prefabricated wall elements according to the invention the middle posts of the wall elements which are provided with tongues above and below consist of rectangular planks the breadth. of which corresponds to the breadth of the subsequent total filling and the inner distance of the laths respectively while their length is somewhat longer than half of the breadth.

According to the invention the dimensions of the jambs are equal among themselves, and the breadth of the jambs is always one third of the breadth of the middle posts and .their length corresponds to half of the length of the middle posts and the breadth of the laths respectively; be-

elements according to the invention corresponds to double their breath, and the laths extend to the end of the grooves .and to the'beginning of the outer tongues respectively.

According to the invention instead of, or in addition to,

the horizontal parallel laths which are at a distance from each other, such laths can be mounted which are diagonal- ..ly directed withrespect to the individual elements.

In the prefabricated wall elements according to the invention laths which are mounted horizontally and parallelly from either side but at a distance from each other on the insulating layers and the middle posts respectively are coated with covers, like slabs, reed mattings with plastering, plaster blocks or other building plates, i.e. over one or more individual wall elements.

A further advantageous embodiment of the assembly with prefabricated wall elements according to the invention consists in that instead of the innermost air layer of the wall elements there is a layer of glass wool, stone wool or mineral wool or the like, even as mattings or preferably packed into bitumen paper, or also plastics, erg. in a foamed condition. The two adjacent layers which are separated by the paling boards can consist of wood concrete, stone wood, sawdustor wood shaving concrete or the like, with or without chemical additions.

Yet a further advantageous embodiment of the assembly with prefabricated wall elements according to the invention consists in that the three layers between the outer laths can be exchanged at random, so that e.g. the inner layer consists of wood concrete, stone wood, sawdustand wood shaving concrete or the like, with or without chemical additions, while the two adjacent outer layers consist of glass wool, stone wool or mineral wool or the like, even as mattings or preferably packed into bitumen paper, or also of plastics, e.g. in a foamed condition, and/ or of air.

A further advantageous embodiment of the assembly with prefabricated wall elements according to the invention, especially the production of the. individual elements, consists in placing through paling boards of minor thickness on the inwardly directed jambs of both middle posts and are correspondingly secured on these inner jambs, whereupon a layer of glass wool, stone wool, mineral wool or the like, even as mattings or preferably packed into bitumen paper, or also of plastics, e.g. in a foamed condition, is mounted on the paling board, and thereafter the wood laths, which connect the middle posts and extend to their outer grooves and/ or tongues, are mounted on the mattings or the plastics, and then the so semiprefabricated element is turned around and also from the other side the same paling boards of minor thickness are placed on the opposite innerjambs'and are secured thereon, whereafter boards or plates of wood concrete, stone wood, sawdustor wood shaving concrete or the like, with or without chemical additions, are mounted on these paling boards, whereupon the above-mentioned wood laths are also mounted on these insulating layers in the same manner and the two-side covers are fixed on the laths.

A further advantageous embodiment of the assembly with prefabricated wall elements according to the invention, especially when assembling the individual elements, consists in making the lower and upper socles of simple square pieces of lumbers of the breadth of the middle posts and without grooves, whereas the middle posts are not provided with the lower and upper tongues, but the lowest as well as the uppermost laths lap vertically over the above-mentioned square lumber, and the said laths preferably extending to the height of the square lumber are in a simple manner nailed, screwed, stuck or joined together.

The wall elements prefabricated in series for the assembly according to the invention are principally connected by laterally joining the individual wall elements in their tongues and grooves and the corner posts respectively, which are in principal also provided with the corresponding tongues and grooves. Further features, advantages and possibilities of application of the invention appear from the accompanying illustrative examples, and from the following description.

FIGURE 1 shows in section an elevational view of a wall element according to the invention, taken on line AA of FIGURE 3,

FIGURE 2 shows in section a corner connection according to FIGURE 1,

FIGURE 3 is a perspective view of two wall elements according to the invention with the appropriate lower and upper socles which have not yet been connected.

FIG. 4 is similar to FIG. 3, differing from the latter in that laths are disposed diagonally.

FIGURE 1 represents an individual element the opposite middle posts of which are designated by 1, the breadth by b and the length by 1 The length 1 is somewhat longer than half of the breadth b Inner vertically directed jambs 2a are laterally nailed or otherwise fixed on the broadsides of these posts, while equal, either centrally arranged tongues 2 or grooves forming jambs 3 are alternatively mounted on the opposite broadsides of the posts 1, so that one element can always be pushed into the other, while the breadth b of these tongues and grooves forming jambs 2, 3 is about one-third of the breadth of the middle post 1. The length 1 of the jambs corresponds to half of the length l,.

The middle posts 1 are provided above and below with tongues 1a which are engaged in corresponding grooves of the lower socle 9a and the upper socle 9b respectively; see FIGURE 3.

When producing the wall element, e.g. on a working table, a paling board 4 of minor thickness is put from one side on the inner jambs 2a of two finished lining posts, which are at a distance from each other, and then mounted. Thereafter, glass wool, stone wool, mineral wool or the like, in the form of mattings 5, or preferably packed in bitumen paper, or also plastics, e.g. in a foamed condition, are put on that paling board. These mattings or plastics are then covered by laths 7 which always extend to the middle posts 1 and to the grooves forming jambs 3 respectively which are mounted on this post. The breadth h of the laths 7 corresponds to the length 1 of the jambs 2, 3. The height of the laths 7 is about double their breadth b Thereupon the semi-prefabricated element is turned around and is provided from the other side with a corresponding paling board 4 on which are then mounted wood concrete, stone wood, sawdust and wood shaving concrete 6, with and without chemical additions. Then also this side is covered by the same above described laths 7 and can now in the usual manner be coated with covers from outside, caused by the filling of the body as described in the above example as the innermost layer on air layer L has been formed.

FIGURE 2 shows a corner connection according to the invention which essentially consists of the vertical adjoining post. On this adjoining post 8 the corresponding vertical outer jambs 2, 3 as grooves and tongues are again mounted and the tongues and grooves of the adjacent elements adjoin. The laths 7 close exactly in the inner corner, while the additional laths 7a of shorter length are attached from outside but are mounted in such a manner on the outer corner of the adjoining post that they fit together there.

FIGURE 3 represents a perspective view of two prefabricated elements which have not yet been coated from outside and have not been connected, together with the appropriate socles 9a and 9b in the grooves 10 of which the tongues 1a of the middle posts 1 and correspondingly the prefabricated elements are to be engaged, while the following elements tightly adjoin by means of their vertically directed jambs or grooves and tongues 2, 3. In the following the essential proportions are again cited which are necessary to obtain the strength of the wall elements according to the invention.

(6) height of laths 7=2Xb The essentially increased strength of the assembly with prefabricated wall elements according to the invention is also caused by the fact that the middle post 1 because of its higher dimensions is the loading or beating part of the lining posts, while the attached jambs 2 and 3, 3 represents the connecting pieces forming the tongues and grooves and due to their dimensions have above all the function of holding the construction together.

From this construction of the lining posts which are joined together of 3 and 4 parts alternatively in a simple manner considerable technical progress has been attained, so that the posts according to the invention show in comparison with the known posts on importantly increased carrying power and solidity as can simply be proved by static calculations and tests. The result of the above-mentioned substantial features together with the various insulating materials and the specific lathing is an excellent strength and at the same time an outstanding heat insulation.

An extraordinary saving in labor as well as an exceptional material economy are furthermore effected by the simple nailing, adhering or similar mounting of the lateral jambs on the middle posts in the form of grooves and tongues.

As in connection with the assembly and the production of the elements according to the invention there can mostly be used waste wood or material of poor quality from the wood production and manufacture, like paling boards, sawdust or the like.

Finally the construction according to the invention is largely similar to the construction with stones as various large elements with different strength and heat insulation can always be prefabricated in series. Therefore the elements according to the invention do not depend on a specified size or type.

Consequently outer as well as inner walls can easily and cheaply be produced by means of the elements according to the invention.

Having now described my invention, what I claim is:

Wall structure fabricated from finished parts and comprising frame-shaped, multilayer wall components placed side-byside, each wall component being provided with end posts composed of several parts, one end post being provided with a groove and the other with a spline for joining adjacent wall components, said wall components being further provided at the top and bottom thereof with splines to engage corresponding grooves within upper and lower bordering strips, and face plates being arranged at both sides, the characteristics being (a) that each end post which is provided with a groove comprises a post-core-strut (1) of rectangular profile and two square strips (3), fastened to the strut and forming the groove, and the end post which is provided with a spline comprises a post-core-strut (1) and a square strip (2), fastened to the strut and forming the spline, (b) that there are provided centric machined strips (2a), one such strip at each inside of a post-core-strut (1), at both sides of said strips there being fastened planks (4) which extend from the end post to end post to form an inner'hol- 1 w area and are covered at the outer side with a blocking material (5, 6); (c) that there are provided at the two sides of a post-core-strut (1), which run parallel to the Wall, laths (7) extending horizontally and at a distance from each other and supporting face plates, and (d) that each of the postcore-struts (1) is provided at each upper and lower end with a protruding tenon (1a) which forms the spline engaging bordering strips (9a, 9b) of U-shaped profile and in the shape of a ledge.
